The state of Washington is home to many beautiful lakes and large reservoirs. Lakes are natural bodies of water, while reservoirs are usually man-made lakes created by building a dam across a river. Some natural lakes, like Lake Chelan, have also been changed by dams. You can swim, fish, or boat in some of these lakes, but not all of them.
